BUNDLE-HOLDER FOR BINDERS.

Application filed March 9, 1917.

To all whom it may concern:

Be it known that I, JACOB S. G. Horne, a citizen of the United States, residing in the county of Hutchinson and State of South Dakota, have invented certain new and useful Improvements in Bundle-Holders for Binders, of which the following is a specification.

This invention relates taining bundles of grain upon the delivery platform, or carrier of self-binding har-- vesters until a sufficient number of bundles has accumulated to be discharged at a desired point in the field. The invention is intended more particularly for use upon what are known as push binders or headers and is illustrated in the accompanying drawings as applied to such a machine.

In the drawings:

Figure 1 is a plan view of a portion of a binder having my improved bundle retaining device applied thereto;

Fig. 2 is an elevation of the same;

Figs. 3 and 4 are enlarged elevations of the bundle retainer, Fig. 3 showing the device in holding position and Fig. 1 showing it in dropping position:

Fig. 5 is a detail perspective view of the bundle retainer.

In the drawings, the reference numeral 1 indicates the reel and 2 the binder deck of a self-binding header, while 3 designates the discharging platform or carrier upon which the bundles are intended to accumulate. The working parts of the binder are operated from a driving shaft which is generally geared to the axle of the ground wheels and mechanism is provided, controlled by the operator, whereby the carrier 3 may be intermittently operated, all these parts being well known and forming no part of my invention and being shown, where shown, in a conventional manner only.

In carrying out my invention, I employ a stout rod or beam -1 which is rigidly secured to the support, indicated at 5, for the bundle eiectors mounted upon the binder deck 2. This supporting rod or beam & should be of such material that it will not readily bend under the strain imposed thereon and it extends over the bundle platform, as clearly shown in Fig. 1. To the outer end of the support a, I secure a T-head or coupling 6 which is disposed between the bundle-re taining arms 7 and receives the bolt or pin 8 by which said arms are pivotally mountto means for re- Specification of Letters Patent.

ed. Above the head (5, the arms 7 are brought together and have their extremities pivoted, as shown at 9, to the upper end of a toggle member 10. This toggle member 10 is pivoted intermediate its ends, as at 11, between the upper ends of lower toggle members 12 which are pivoted at their lower ends to the support l, as clearly shown. A stop pin 13 is inserted through the toggle members 12, intermediate the ends thereof, and is so located as to be engaged by the concave seat of face 11 of the free end of the upper toggle member 10. An operating cable 15 is secured to the member 10, adjacent the free end of the same, and is carried therefrom over the bundle carrier and the binder deck and through suitable guiding means to a point where it may be easily reached by the operator or driver, being preferably in practice attached to the foot lever by which the bundle carrier is controlled. A spring 16 is secured to the support 4:. between the ends of the toggle members 12 and the free end of said support, 1

and extends therefrom to the bundle-retaining arms 7 and is attached to the same below the pivot 8 thereof.

It is thought the operation of my device will be readily understood. It will be noted that the device presents a fork or swinging barrier at the outer end of the bundle-car rier or platform which will depend to a point adjacent the surface of the said carrier and will thereby prevent the bundles rolling off the same. The spring 16 normally holds the fork or retaining arms in the position shown in Figs. 3 and 5 and as the bundles pass from the binder deck they will roll toward the outer end of the plat form 3 and come to rest against the arms 7. When a sufficient number of bundles has accumulated, the driver pulls upon the cable 15 and thereby swings the upper toggle member 10 to the position shown in Fig. 1, the lower toggle member 12 moving upwardly into the vertical position shown in said figure and the upper ends of the bundleretaining members being thereby swung inwardly so that the lower ends thereof will be lifted from the carrier which is, at the same time, set in motion and will, consequently, discharge the bundles onto the ground. lVhen the cable 15 is released, the spring 16 at once contracts and returns the parts to the normal position shown in Fig. 8, the free end of the trip 10 impinging against the stop. 13 so that the movement of the parts will be limited and the bundle-retaining members brought to rest in a vertical position, at which time their lower ends will be nearest the surface of'the platform. The form of the upper toggle member and its arrangement relative to the lower toggle member and the bundle-retaining arms causes these parts to serve as a lock in the position shown in Fig. 3 whereby movement of the bundle-retaining arms 7, under pressure from the bundles, will be effectually resisted and the said members will be prevented from swinging outwardly to release the bundles until a positive upward pull is exerted upon the free end of the trip through the cable 15.

My device is exceedingly simple in the construction and arrangement of its parts and will be found highly eflicient for the purposes for which it is designed.

Having thus described the invention, what is claimed as new is:

1. The combination with a harvester, and a bundle carrier, of a support secured on the harvester and extending over the bundle carrier, a bundle retainer pivotally mounted on the support, a lower toggle member pivoted upon the support, an upper toggle member pivoted at one end to the bundle retainer and intermediate its ends to the lower toggle member, a stop on the lower toggle member to be engaged by the free end of said upper toggle member, means for actuating the toggle members, and yieldable means for holding the bundle-retainer in a set position.

2. The combination with a harvester, and a bundle carrier, of a support secured on the harvester and extending over the bundle carrier, a retainer pivoted upon the support and extending above and below the same, a

lower toggle member pivoted to the support adjacent the retainer, a stop intermediate the ends of said toggle member, an upper toggle member pivoted at one end to the upper end'of the retainer and intermediate its ends to the upper end of said lower toggle member, the free end of said upper toggle member at times engaging said stop, and an operating cable attached to said upper toggle member near the free end thereof.

3. The combination with a harvester, and a bundle carrier, of a support secured on the harvester and extending over the bundle carrier, a head at the free end of said support, a retainer carried by said head and pivotally mounted thereon, a spring having one end secured to the support and its opposite end secured to the retainer below the pivotal point of the same, an upper toggle member pivoted at one end to the upper end of the retainer, a lower toggle member pivoted at its lower end to the support and having its upper end pivoted to said upper toggle member intermediate the ends thereof, a stop on said lower toggle member to be engaged by the free end of the upper toggle member, and a cable attached to the upper toggle member at the free end thereof.

L The combination with a harvester, and a bundle carrier, of a support secured on the harvester and extending over the bundle carrier, a barrier pivoted on said support and depending therefrom to the bundle carrier, yieldable means connecting the barrier with the support for holding the barrier in a set position, a toggle mechanism mounted on the support and normally holding the barrier against movement, and means acting on the toggle mechanism to release the same and actuate the barrier. 1

In testimony whereof I aflix my signature.
